AD5696RBRUZ-RL7

Overview

The AD5696RBRUZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and a user-selectable gain of 1 or 2 via the GAIN pin. The device operates on a single 2.7 V to 5.5 V supply and communicates through a 400 kHz I2C-compatible serial interface. Key specifications include ±2 LSB maximum relative accuracy (INL), ±0.1% FSR total unadjusted error, and a high drive capability of 20 mA. It supports power-down modes reducing current to 4 µA and includes per-channel reset options.

Feature Summary

• Quad 16-bit resolution with ±2 LSB maximum INL
• Internal 2.5 V reference with 2 ppm/°C typical drift
• User-selectable gain (×1 or ×2) for flexible output ranges
• 400 kHz I2C-compatible serial interface with 1.8 V logic compatibility

Applications

• Optical transceivers
• Base-station power amplifiers
• Process control (PLC I/O cards)
• Industrial automation
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'RL7' against the manufacturer's ordering guide to confirm reel packaging details. Ensure the B grade specification requirements match the application needs. Confirm that the TSSOP-16 package dimensions align with the PCB footprint design. Check for any RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when a quad-channel DAC with high precision and low drift is required. The internal reference simplifies design compared to external reference parts. Consider the gain setting; Gain = 2 requires VDD to be at least VREF + 1.5 V. Verify that the I2C address pins (A0, A1) can accommodate the system addressing scheme.

Part Context

This part belongs to the AD5696R/AD5695R/AD5694R family, which shares the same pinout and interface but differs in resolution (16-bit, 14-bit, and 12-bit respectively). The 'B' grade indicates tighter performance specifications compared to the 'A' grade. The 'RUZ' indicates the 16-lead TSSOP package, while 'RL7' denotes the tape and reel packaging format.

Replacement Considerations

The AD5696BRUZ is the non-'R' version of the same device in the same package. The AD5696BCPZ-RL7 offers the same electrical characteristics in a 3 mm × 3 mm LFCSP package. Cross-referencing with the AD5696R datasheet is recommended to ensure pin compatibility and parameter alignment.
